δ-Amyrone, a specific inhibitor of cyclooxygenase-2, exhibits anti-inflammatory effects in vitro and in vivo of mice.[Pubmed: 24813716]

δ-Amyrone (13(18)-Oleanen-3-one), a pentacyclic triterpene compound from S. lineare Thunb, was found to possess a potent anti-inflammatory effect in different inflammation model animals. Pretreatment with 13(18)-Oleanen-3-one (i.p.) inhibited the ear edema in xylene-induced mouse ear edema. 13(18)-Oleanen-3-one also decreased the level of nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-6 (IL-6) and leukocyte numbers in acetic acid-induced peritonitis in vivo. To clarify the possible mechanism of 13(18)-Oleanen-3-one, we investigated the effect of 13(18)-Oleanen-3-one in lipopolysaccharide (LPS) induced peritoneal macrophages. The data indicated that 13(18)-Oleanen-3-one notably inhibited IL-6, TNF-α and NO production. In addition, the result showed that 13(18)-Oleanen-3-one may control the cyclooxygenase-2 (COX-2) regulation and not the cyclooxygenase-1 (COX-1) at protein levels. These results suggest that 13(18)-Oleanen-3-one is a bioactive agent which possesses anti-inflammatory effects, which may be relevant to the regulation of COX-2.
